Indian gooseberry (Emblica officinalis Gaertn) commonly known as aonla is one of the important fruit crop in arid and semi arid growing regions. To see the effect of different bioagents alone and alongwith effective fungicide against aonla rust, a field experiment was conducted. Pooled data revealed that chlorothalonil (0.2 %) reduced the maximum disease intensity significantly in comparison to control and other treatments. Minimum disease severity (5.80%) was obtained in chlorothalonil (0.2 %) followed by 1% Trichoderma viride +0.1% chlorothalonil (8.82 PDI). Maximum per cent disease control (71.80) was obtained in chlorothalonil (0.2 %) followed by 1% Trichoderma viride + 0.1% chlorothalonil (57.12) and also increased fruit yield significantly in comparison to other treatments. Maximum B: C ratio was obtained with chlorothalonil 0.2% (1:1.38) followed by 1% Trichoderma viride + 0.1% chlorothalonil (1: 1.29).

Abstract

Combining ability studies on growth and yield components were conducted from 10 × 10 half diallel cross of brinjal. The analysis of variance for combining ability selected revealed that mean squares due to GCA and SCA variance were significant for all the characters which indicated that all the characters were controlled by both additive and non-additive gene effects. However, the σ² _gca/σ² _sca ratio being less than unity for all the characters except fruit diameter and plant height indicating that the non- additive gene action was more important in the inheritance. Among the parents, based on fruit yield DBSR-91, followed by DBR-31 were found to be best general combiners, DBSR-91 was found to be best general combiner over all the characters. DBR-31 was found to have desirable GCA effects only for plant height, crude protein content besides fruit yield. Pusa Purple Round x Pusa Kranti followed by DBR-31 × Pusa Kranti, HLB-12 × DBR-31, Hisar Shyamal × Pusa Purple Round and HLB-25 × DBSR-91 were the best crosses based on SCA effects of fruit yield.
